Ok, so I’ve ventured into the garage again… and stripped down the mullered wiring loom to try and work out what I can do to convert a 6 pin ignition switch into a 7 pin plug on the loom. Whilst industrious, the person who “converted” the loom to key fob switches instead of regular, has 1) used at least a whole roll of black insulation tape to hide his ferklings, AND 2) done a hideous job!
Time to get my diagrams out again! (In Portuguese 
)
Cut the red wire.
NO, THE GREEN ONE…
Oops.
Looks like it’d be easier to start over and make your own loom.
I’ve got another loom, I’m trying to work out what is essential on the ignition switch…
The loom has an 8 pin connector (with 7 used pins)
The switch I have has a 6 pin connector with all pins used.
I’m trying to work out what is the best way to chop it. Put a 6 pin on the loom, or an 8 pin on the new switch. I’ve now got an English wiring diagram, so I don’t have to worry about about the mullered one now!

Still have to sit and think a while before cutting!
Edit- weirdly, can’t find the wiring diagram for the switch I have, so today I must get the multimeter out and make a connector block diagram.
Right… so buggering about has led to this…
If my brain is working here… I should be able to use the loom as standard; convert the new switch into the 8 pin socket, but have the red and black wire come straight out to a separate switch and then feeds back into the red pin.
This making effectively a 7 pin switch as the original?
Am I making sense, or are the voices misleading me?
Pretty hard for my small brain to see what you are trying to do but why don’t you just join the red/black wire to the red?
I don’t know what PA is but is it because you want to be able to turn the park light on/off by an external switch? If so then just put a switch on the Park Light live wire to ground.
I think 
I’m sorely tempted to do just that, but the bike is electric start only, so I don’t want to create any chance of a battery drain by my inability to interpret writing diagrams competently… by adding the standalone switch, I recreate (I think) the original wiring
Before youTOUCH that lot have you got a ‘power probe’? This is the one tool I can not work without. It’s my magic tool as it not only tells you the current in an unidentifiable wire if it’s negative or positive but it also can shoot a current down it too or even a negative. I bypassed my engine starter from the CAN- bus system with it on my 2013 Bonneville and made a new link so the system always started no matter what the brain box got angry about
In fact I’ve just rewired a fire damage loom on my car with around 80 multiple thickness wires.
I just have a standard multimeter… but don’t worry… I am pretty certain that with the donkey 
wiring that muppet did going straight in the bin now… I’m already in a more comfortable place.
